Abstract: In a service mesh, back-pressure is applied and relieved as needed by a control mechanism which is applied between pairs of services to control the rate at which service requests are made from one of service to the other via monitoring hardware and/or software metrics. A proxy of one service is monitored to observe the rate at which it receives service requests from the other service. If it is observed that the monitored metrics have breached allowable limits, back-pressure is applied to reduce the rate at which the other proxy transmits these service requests. Through continued monitoring of the proxy, the back-pressure can be later relieved when appropriate by increasing the permitted request rate.
